Silicon Valley Investors Back Aschenbrenner After Unwind

Several technology and venture-capital investors sought to put money into Situational Awareness days after the fund was forced to unwind heavily leveraged positions. The firm has told prospective investors it is not taking new capital.

Situational Awareness concentrates on AI-related equities. Recent market stress magnified losses on large borrowed positions, and the fund pared back those stakes. The firm had used leverage and held a compact set of positions, which increased its exposure when prices moved against them.

In a letter to investors, Leopold Aschenbrenner wrote that the firm had eliminated leverage for the time being, acknowledged the episode had been costly and said the experience would provide lessons for the team.

Several backers in the San Francisco Bay Area who invested at the fund’s launch — mainly wealthy individuals and family offices rather than large institutional investors — signaled continued support. Pat Grady, a partner at Sequoia Capital, expects Aschenbrenner to remain an important figure in Silicon Valley for years to come.

Major banks provided financing and prime-brokerage services to the fund. Goldman Sachs, JPMorgan and Bank of America extended credit or services. Barclays’s prime-brokerage unit declined to take the fund on before the troubles, citing concerns about heavy concentration in a single sector. Morgan Stanley initially declined to provide prime services because of Aschenbrenner’s limited hedge-fund experience, but later reconsidered and prepared to onboard the fund.

Bank risk teams and prime brokers raised concerns about concentrated portfolios, the use of leverage and limited risk-management experience. Those concerns shaped some banks’ decisions not to engage with the fund and led others to monitor or restrict exposure as positions became stressed.

Aschenbrenner’s letter called for more disciplined risk controls and said the firm would reassess its approach to leverage and concentration. The fund will operate without leverage for now. Managers will need to stabilize positions, seek committed capital and adjust governance and risk practices to meet prime-broker expectations and investor requirements.
